Also known as:
Neotropical Whip Snake
Subspecies I've seen:
Masticophis mentovarius striolatus
Huatabampo, Sonora, Mexico—August 22, 2017
As two carfuls of herpers headed to the gartersnake zone
, this big snake interrupted the quest by meandering across the road. Andy O'Connor jumped out of his car and pounced, which was wise because these snakes are very fast, but not entirely wise because they also have very sharp teeth and a propensity to bite. However, if memory serves, Andy was uninjured, and the snake was detained for a photo session that took place after we found those gartersnakes.
During said photo session, the whipsnake demonstrated that combination of teeth and propensity all over the hand of Gerrit Jan Verspui, who was helpfully wrangling the snake for the rest of us. The hand in question gushed blood dramatically for quite a while. Gerrit enjoyed the excitement, and we all appreciated his snake wrangling. Thanks Gerrit! I hope your hand eventually healed!
